lM PROVEM ENT IN BOTTLE-STOPPERS.

Specification forming part of Letters Patent No. 202,434, dated April16, 1878; application filed March 1, 1878.

To all whom it may concern:

Be it known that I, GEORGE W. GOMBER, of Hazleton, in the county ofLuzerne and State of Pennsylvania, have invented a new and ImprovedBottle-Stopper, of which the following is a specification:

1n the accompanying drawing, Figure 1 represents a front elevation of myimproved bottle-stopper, being partly in section through thestopper-head and cap. Fig. 2 is a side View of the same, and Fig. 3 is adetail side view of the flexible stopper.

Similar letters of reference indicate corresponding parts.

This invention has reference to such llIlprovements in the well-known DeQuillfeldt bottle-stopper patented January 5, 1875, that the same workswith greater efficacy, swings with greater reliability, and is moredurable and more easily worked than-heretofore.

The invention consists of a diametrical partition in the metalliccap-piece hung to the lever-acted yoke, in connection with a flexiblestopper whose shank has a recess corresponding to the partition.

It consists, secondly, of a semicircular neckband with bent ends orears, to which the outwardly-bent pivot ends of the eccentric-lever areapplied, the neck-band being retained by a wire passing throughperforations of the band back of the ears.

Referring to the drawing, A represents an eccentric-lever, B the yoke,and O my im proved compound stopper. The eccentric-lever is hung to ametallic neck-band, D, and the compound stopper 0 to the horizontal toppart of the yoke. The compound stopper is constructed of an elasticstopper-disk, a, with laterally-perforated stem or shank b, and of arigid cap-piece, d, that is provided with a lat eral perforation anddiametrical partition, 0. The partition is perforated for the passage ofthe yoke, in line with the lateral perforation of the stem of thestopperdisk, the stem being furthermore centrally recessed, so that thepartition of the cappieoe fits into the stern, and the symmetricalsections of the stem enter into the cavities at both sides of thepartition. The upper rounded-ofi'part of the partition projects slightlyabove the upper part of the stem-sections, and protects the same blows,&c., and also against the strain exerted in operating the stopper, itforming thus an essential feature of rendering the compound stopper moredurable. and effective.

The stopper-disk a is provided at the under side with a bulged or raisedportion, a, that corresponds in size to the mouth of the bottle,

and admits thereby the closing of the. bottle in easier and quickermanner, as the stopper assumes always the same position in the center ofthe mouth of the bottle. The bulge of the stopper-disk is forced intothe mouth of the bottle when the stopper device is closed, so as toproduce a perfectly tight connection therewith.

The neck-band D is made of a metallic band, of semicircular shape,provided with slightlybent or offset ends or ears f, to which theoutwardly-bent ends of the eccentric-lever A are pivoted. The neck-bandis perforated back of the ears, and a fastening-wire, g, drawn throughthe perforations and twisted at the ends in the usual manner, so as torigidly retain the neck-band on the bottle. The eyes of theeccentric-lever, to which the yoke B is pivoted, are bent in such amanner as to place two thicknesses of wire sidewise of each other at therear part of the eyes, and furnish thereby a better bearing for thethumbs on opening the stopper. The perforated ears of the neckband forma superior support for the pivots of the eccentric-lever.

The stopper is operated in the same manner as the De Quillfeldt stopper,but is more durable, on account of the improved construction of thecompound stopper and the superior hanging of the eccentric-lever on theneckband- Having thus described my invention, I claim as new and desireto secure by Letters Patent? 1. A bottle-stopper consisting of theelastic disk a, having vertical recess and lateral per-v A forated stem11, end the cap 01, having later- 3. Inabottlestopper, the combination,with ally-perforated diametrical partition 6, raised the stem-disk a band cap d, of the partition 6, a little abovethestem,as shownanddescribed. supported in a slot of said stem, as and for 2. Themetallic neck-band consisting of the purpose specified.

semicircular piece D provided with bent ears f, perforated to receivethe end of lever A, GEORGE GOMBER and a twisted Wire, 9, drawn throughperfora- WVitnesses:
